Specification of Letters Patent.

Patented April 3, 1906.

Application filed May 23, 1905. Serial No. 261.781.

To aZZ whom it may concern."

Be it known that I, J onN W. MILLER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Well-Drilling Machines, of which the following is a specification.

This invention relates to portable machines for drilling oil, gas, and other deep wells.

The object of this invention is to provide improved mechanism for actuating a drillingcable in the operation of spudding and to make said mechanism adaptable for beamdrilling, as desired.

The invention further contemplates providing an improved means for actuating the drilling-cable so as to accelerate its downward or working stroke and make its ascent therefrom relatively slow or gradual.

With the foregoing and other objects in view the invention consists in the novel construction, combination, andv arrangement of parts constituting the invention, to be hereinafter referredv to, and illustrated in the accompanying drawings, which form a part of this specification, in which is shown the preferred embodiment of the invention; but it is to be understood that changes, variations, and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings, in which similar referencenumerals indicate like parts in the different figures, Figure 1 is a perspective view of so much of a well-drilling machine as will illustrate the adaptability of this invention thereto. Fig. 2 is a plan view of the rear portion of the frame and mechanism shown in Fig. 1, and Fig. 3 is a section of Fig. 2 at the line X.

In the drawings the reference-numerals 1 1 indicate the two side beams constituting a portion of the horizontal frame of the machine. This frame is suitably mounted upon ground-wheels 2 2, by which the machine is transported. Mounted between and supported by the rear end of the beams which constitute the frame is an ordinary steamboiler 3 of any preferred type suitable for this style of machine. On one of the beams 1 is mounted a samson-post l, on the upper end of which is pivotally mounted a walkingbeam 45 and having attached to its left end a pitman 5. On. the front ends of the beams 1 1 is mounted a mast or derrick 6, braced from the rear by bars 7. Extending between the beamsand usually located on either side of the place where the samson-post is located are two cross-bars 8 8, and mounted on these bars 8 S is an ordinary upright engine 9, adapted to revolve a horizontal shaft 10, having a large balance-wheel "12 at one end and a pulley 11 at the opposite end.

Mounted in bearings 12 12 on the beams 1 1 immediately in front of the boiler 3 is a transverse shaft 13, having on one end a large pulley 14, over which is passed a belt 15, which also passes over the pulley 11 on the engine-shaft 10. Power is communicated to the shaft 13 by means of the belt 15 actuating the pulley 1. 1. The front end of the shaft 13 bears a crank-arm 16, provided with a wrist-pin 17, having mounted thereon shoes 18.

Mounted on the beams l 1 and in front of the shaft 13 are a pairof bearings 21, inwhich is mounted for rotation a shaft 20. This shaft bears at one end a twopart crank-arm,

consisting of a rigid member 19, fixedly secured to the shaft and havingcut in its extended portion a groove 19. Attached by means of cap-screws 19 to the arm 19 is a strap 19", which constitutes the other part of said crank-arm, and this strap converts the groove 19 into an elongated slot, which is adapted and arranged to receive the wristpin 17 and its shoes 18.

Rigidly secured on the shaft 20 is an oscillating arm 22, hearing at its upper end a spudding-sheave 23, arranged to engage and operate the drilling-cable.

Mounted in bearings 24 on the beams 1 1 is a shaft 25, bearing 011 its nearer side a large spur-gear 26, and in its central portions between the beams 1 1 a reel 27. Meshing into the spur-gear 26 is a shrouded pinion 28, mounted 011 a shaft 29, supported in bearings .19), mounted on the beams 1 1. The shaft 29 where it passes through its bearing on the farther beam 1 is inclosed by an eccentric sleeve 30, to which is attached on the farther side of the bearing an arm 31, and to the upper end of this arm 31 is attached a rod 32, having a handle 33, by which it is operated. Beyond the arm 31 the shaft 29 bears a friction-pulley 3 1 of such a diameter that when the arm 31 is thrown in one direction the eccentric sleeve 30, in which is mounted the shaft 29, will force the face of the pulley 341 against the outer face of the belt-pulley 14 and cause frictional engagement between these two. I

Mounted on a housing, extending between the cross-bars 8 8, is an idler-sheave 36, over which the drilling-cable is passed in its course from the reel 27 to the oscillating sheave 23, and from there it passes upward over a sheave in the top of the mast or derrickand from thence downward into the well in the ordinary manner.

A reel 37 is placed on a shaft 47, mounted in bearings 18 on the beams 1 1, and around this reel is passed a sand-pump cable 38. The shaft 47 on which the reel 37 is mounted, is provided with an eccentric sleeve 16 in its bearing, which sustains it on the farther beam 1 in precisely the same manner as the shaft 29 is surrounded by the eccentric sleeve 30, and a rocking arm 39 is attached to this eccentric sleeve. This eccentric sleeve and the bearing in which it is revolved is hidden by the side of the reel in Fig. 1 but as its operation is exactly the same as the eccentric sleeve for the shaft 29 it is believed that a further description of it is unnecessary. This shaft 17, which bears the reel 37, has a pulley 40, which is arranged to engage the inner face of the pulley 14L to one side of the spokes thereof in the same manner that the pulley 34 engages the outer face of the pulley 1 1. The operating-arm 39 is provided with a connecting-rod 41, having a handle at a convenient place to be operated by the engine attendant.

The operation of this device is as follows: In ordinary beam drilling the two part crank-arm is disengaged from connection with the wrist-pin 17 by removing the capscrews 19 and separating the member 19 from the arm 19 and removing the wrist-pin 17 and its shoes 18 from the crank-arm 16. A wrist-pin is then inserted in one of the openings 50 shown to exist in the crank-arm 16 and the end of the pitman 5 fitted over this pin and ordinary beam-drilling may be practiced as long as desired.

In using this device for spudding the parts will be in the position indicated in the drawings and the drillingcable will pass from the pulley on the top of the mast or derrick down around the spuddingsheave 23 and from thence around the idler-sheave 36 to the reel 27. The revolution of the large pulley 14, driven by the belt 15 from the engine-pulley 11, will reciprocate the wrist-pin 17 and its shoes 18 in the slot 19 formed in the arm 19, causing an oscillating motion to be imparted to the arm 22 on the shaft 20. This arrange ment just described is such that a quick downward movement or stroke is imparted to the arm 19, and as this movement allows the loosening or slackening of the working cable it imparts a quick downward stroke to the tool suspended on this cable, which is a very desirable effect to be produced in welldrilling machines of this character, and as the crank-arm-16 continues its revolution the effect will be to cause a relatively slow moveerases ment of the oscillating sheave when raising the tools for the next stroke. sired to raise tools from thewell, the handle 33 is drawn forward, swinging the bar 32 and the arm 31 on the eccentric sleeve 30, which throws the face of the pulley 34 into frictional engagement with the face of the pulley 14, causing a rotation of the pinion 28,

which on account of its meshing into the large spur-gear 26, revolves the reel 27, winding up the working cable, and thus raises the tools from the well.

It will be further noted that the shaft 13, on which is the crank-arm 16, the shaft 20, on which is the rocking arm 19, the main reelshaft 25, on which is the spur-gear 26, and the pinion-shaft 29, bearing the pinion 28, are all mounted conveniently above the side beams 1 1, so that none of the mechanism used in the operation of drilling is placed below the frame of the machine. This arrangement of the operative parts of the machine is one of great importance in this species of machine for this reason, that, as has been before stated, the machines are portable and are transported over roads at all seasons of the year, some of which are so muddy that the machine will frequently sink therein to the under sides of the beams 1 1, and if the operative mechanism is placed below these beams 1 1 there is great liability of breaking or injuring the same when passing over even ordinarily fair roads. It will be further noted that the arrangement of the parts in this de vice are of unusual simplicity and as the mechanism of well-drilling machines is handled in the field distant from repair-shops simplicity, ease of manipulation, and repair become of prime importance to the user of this class of devices, and, further, the extreme simplicity of the device gives to the manufacturer thereof the opportunity to make the working parts which are subjected to great strain or unusal weight of greater strength to resist the possibility of accidental breaking.
